3×x_{1}  4×x_{2} + 5×x_{3} + 8×x_{3} = 56 


The variables s_{1} and a_{1} will be part of the basis of the initial Simplex Tableau (for Phase 1)
Since we added artificial variables, we need to use the 2phase Simplex method to drive the artificial variables to ZERO (0) to obtain a feasible basic solution before starting with the actual Simplex method (phase 2)
